采用分析气相色谱法、银离子高效液相色谱法和气相色谱/质谱法测定了黑海Dysidea fragilis海绵的脂肪酸组成。研究人员发现了100多种不同的脂肪酸，其中许多与热带海洋海绵中的脂肪酸相似。另一方面，一些已确定的脂肪酸以前在海绵或其他海洋来源中没有发现，可能是科学上的新发现。这些包括13-甲基-十四碳-4-烯酸和14-甲基-十六碳-6-烯酸，以及海绵酸，即5，9，17-二十四碳三烯酸、5，9，17-二十五碳三烯酸和5，9，19-二十五碳三烯酸。从银层析的洗脱行为来看，所有的双键都是顺式构型。
The fatty acid composition of the sponge, Dysidea fragilis, from the Black Sea has been determined by analytical gas chromatography, silver ion high-performance liquid chromatography and gas chromatography/mass spectrometry. More than a hundred different fatty acids were identified, of which many were similar to those in sponges from tropical seas. On the other hand, some of the fatty acids identified have not been found previously in sponges or other marine sources and perhaps are new to science. These include 13-methyl-tetradec-4-enoic and 14-methyl-hexadec-6-enoic acids, together with demospongic acids, i.e. 5,9,17-tetracosatrienoic, 5,9,17-pentacosatrienoic and 5,9,19-pentacosatrienoic acids. From the elution behavior on silver nitrate chromatography, all the double bonds were of the cis-configuration.
